- Delivery is at least once and unordered. Receivers should verify the raw body, deduplicate by Webhook-Id, and return a 2xx response quickly.

- Public pricing is shown by searches first. A secondary units view remains available.

- Units are active subscription capacity. They are released when a search is deactivated.

## Best fit
- People tracking specific items, models, price ranges, and local areas across supported marketplaces.
- Buyers, resellers, collectors, renters, and small businesses that want alerts routed to mobile push, Telegram, Discord, email, Web Push, or their own secure webhook endpoint.
- Users who want search parameters, Custom URL mode for advanced single-platform searches, include and exclude rules, AI relevance filtering, and filtered listing review before tuning a search further.
- Teams or individuals who want one alert app across web, iOS, and Android instead of a browser-only or manually refreshed saved search workflow.

## Not a fit
- Users who need every listing from every marketplace to be covered.
- Users who need a marketplace account automation tool, checkout bot, or scraper that uses their marketplace login.
- Users who only want marketplaces that Classifindr does not currently support.
- Users who need a free unlimited monitoring product with no checkout minimums.

## Important limitations
- Monitoring is best effort and depends on supported marketplace availability, listing visibility, search configuration, and selected check speed.
- Alert timing depends on when a listing appears relative to the next check, marketplace availability, and the notification channel.
- Classifindr does not claim complete detection or complete coverage.
- Classifindr does not ask for or store marketplace login credentials.
- Webhook delivery is at least once and unordered. Verification proves signed reachability, not ownership of the destination.
- Classifindr is independent and is not affiliated with Auto Trader, CarGurus, Cazoo, Facebook Marketplace, Gumtree, Craigslist, Trade Me, Kijiji, OfferUp, Poshmark, Pinkbike, Vinted, eBay, Mercari, or Chrono24.
